ADVERTISING DISPLAY DEVICE.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed October 29, 1913. Serial No. 798,015.

To all whom it may concern Be it known that I, JosEPH ALFRED PROULX, acitizen of the Dominion of Canada, residing at Vancouver, in theProvince of British Columbia, Canada, have invented certain new anduseful Improvements in Advertising Display Devices, of which thefollowing is a specification.

This invention relates to a mechanically operated advertising device ofthat class wherein advertising display cards or the like are arranged onedge in two groups within a suitable frame to expose the face of thecard at each end of each group, the end card of one group beingtransferred to the other at the back and front alternately, so thateach.

face of each card in the two groups is displayed for a sensible intervalof time.

The invention comprises the particular construction of the card holdingframes with provision to facilitate movement of the frames, both in theplane of the face, as when transferring from one group to the other. andin a direction normal to that face, as when traveling from back to frontand from front to back in the groups.

Theinvention comprises also the mechanism by which the advertising cardframes are transferred laterally from one group to the other with thenecessary pause through a definite period of time for exhibit of theadvertisement displayed on the several cards, and the manner pressure tothe front of one group and to the back of the other, which springpressure moves the card frames of each group to fill the space occupiedby the frame transferred to the other group.

The invention is particularly described in the following specification,referencebeing made to the drawings by which it is accompanied, inwhich? Figure 1 is a. front elevation of the machine showing the same inits completed arrangement. Fig. 2 is a section taken substantially onthe line 22-of Fig. 1, those frames on the right side being shown inplan. Fig. 3 is a detail view in the plane of line 3.-3 onFig. 1. Fig. 4is a perspective viewof an advertising card frame. Fig. 5, an enla-rgeddetail showingthe relation of the card frame with its transferringchain, and Fig. 6 is a plan of the machine frame showing the geararrangement. Fig. 7 is a detail section on the line 7+7 of Fig.- 2.

In these drawings2. represents an open of applying a spring frame withinwhich two groups 3 and a of advertising card frames 5 are carried.Extending across the back and the front of the frame 2 and within it areupper and lower transfer rails 10, each composed of two light bars whichat the ends, where attached to the frame 2, have distance pieces tomaintain them a short distance apart to allow the transferring mechanismto project between them, Extending across between the lower transferrails under each group 3 and 4 are cross rails 11 which sustain the cardframes 5 and allow them to move backward in one group and forward in theother group along them.

Immediately outside the transfer rails 10, the machine,

both in the back and front of and projecting a short distance above themare face rails 12, against which the card frames 5 of each group areheld by the pressure of a spring at the opposite end of the group, whichspring will be described later.

In the line of division between the two groups 3 and 4, and at adistance from each face rail 12 corresponding to the thickness of a cardholding frame 5, rollers 18 are mounted, which rollers may be adjustablein their distance from the face rail.

Within each card holding frame 5 an ad vertising display card 6 may beinserted in amanner providing for ready removal and change. Each framehas transverse rollers 7 in its upper and lower rails to facilitatemovement along the transfer rails 10, and adjacent to these rollers arerollers 8 to bear on the cross rails .11 during movement along therails. The rollers 7 should project a little farther out of the framethan the rollers 8, to sustain the latter clear of the rails 10 whiletransferring, and the upper side of the cross rails 11 should beslightly above the transfer rails 10. In the opposite face of eachrail'of the card frame 5 a roller 9 is inserted at each end, whichrollers are designed to relieve the frame of friction with the facerails 12 and with the adjacent frame while a frame is being transferredfrom one group to the other. The vertical edges of the frames arerounded, as at 14:, or are beveled from each face to facilitate entranceof the frame between the face rails 12 and the adjacent frame on thetransfer from one group to the other. Secured to and projecting outwardfrom each face rail 12 in alinement with the middle line of each group,studs 15 project outward from the front of one roup and from the backof" the other group. On each stud 15 a roller carrying bar 16 is freelymounted and is pressed toward the face rail by a spring 17. The ends ofthis bar are turned toward the face rail 12, and on each end a smallroller 18 is mounted, each roller passing through an aperture providedforit in the face rail to bear against the outer face of the card frame.The action of this roller bar isillustrated on the right hand side ofFig. 1, where a card frame 5 is shown in the act of transfer in thedirection of the arrow from the group 4 to the group 3. As will there beseen the edge of the frame is inserted, between the roller 18 and theroller 13, or the roller 9 of the adjacent card frame, and the springs17 top and; bottom, are, pressed back withthe two to onefleverage of theroller bar 16, and as the leading edge of the transferring frame reachesthe other roller 18, it is also forced back-with the two to oneleverage, and the springs 17 then exert a distributed pressureover thewidth of the. frame, pressing all the frames of that group against .theface rail 12 at the back of the machine. As the face rollers 9 of thecard frames are in one face of the top rail and in the opposite face ofthe bottom, rollers 38 should be provided in the top or bottom face rail12,. as the arrangement may require, at the opposite end of each groupto the spring rollers 18.

The transfer of a card holding frame 5 from the left hand group 4 totheright hand group 3, at the front, and from the right hand group to, theleft hand group, at the back, is effected by ing a projection 22 fromone of its links which projection passes through between the transferrails 10 and into engagement with either end of a recess 23 in themiddle of the top and bottom rail of the frame 5 which may occupy aposition on these rails;

One chain 20 is arranged under the lower and one over the upper rails 10at the front of the machine and under and over the rails lOat the backand each chain passes around a jtriangularly arranged group of sheaves21,24 of which 2 1- is a driving sprocket and 21 are only guide sheavesmaintaining a length of the chain parallel to the rails 10..

i As shown in the drawing, the card carrying frames travel from left toright at'the front and from ri ht to left at the back and as "the topand bottom drive is taken from adjacent sides of the opposed chains, the

7 chains must travel in opposite directions of rotation.

r The alternating movement which'it'is desired shall be imparted to thecard frames at the front and the back of the machin'eis attained byplacing the engaging projection 22 of the top and bottomchains 20whiclran endless chain 20 havmove the card frames at the back in an oppositeposition on the chains to what they are in the front. The chains 20 areoperated from a first motion shaft 25 which de rives its movement fromany convenient source of power, and the required period of movementalternating with a period of rest is derived from this shaft 25 by anendless chain 27 taking around a sprocket wheel 26 secured on the shaft25 andaround a flanged sheave 28 secured on a shaft 80 rotatablymountedin the lower part of the frame 2 of the machine on oneside. Thechain 27 passes loosely around this sheave 28, the flanges of which areprovided with diametrically. opposed projections 32 to engage pins 31projecting from certain links of the chain 27 at a distance apart equalto the circumferential distance apart of the projections 32 of thesheave. The chain 27 will thus move loosely on the sheave 28 withoutdriving it until its pins 31 successively en-v gage the projections 32of the sheavewhen the shaft 30 is rotated through a complete revolution,each. pin .hrotating the" sheave through a half revolution beforeleaving it. If a shorter period of rest between movements is requiredthan is obtainable with 7 two pins in the length of the chain 27,.two

other pins may be provided at the required distance apart to give theperiod'of rest required. To insure that thedriving pins 31 do not freethemselves from engagement with the projections 82 until each hascompleted the definite movement required of it, a guard 33 is secured tothe frame of the machine which will hold the-projecting pins in drivingengagement with the projections of the sheave until the full movementreleases them from such engagement. The intermittent movement impartedtotthis shaft 30 is conveyed to the several chains 20by a chain 34:taking around asprocket wheel 35 secured on the shaft 30 and around asimilar wheel 36 secured on a shaft 37' extending across the other endof. the "machine. On

the other end of this shaft 37 is secured a sprocket wheel lO from whicha chain e1 is carried around a sprocket .wheel42 secured to rotate withthe driving sprocket 24: of the sprocket wheel at), around which passesa chain 47 which takes alsoaround the sprocket wheel 42 of the drivingsprocket 2 1 of the lower chain 20' atthe front of themachine.

The interposition, of the' gears tiie l-reverses the direction of'imovemeiit of the:

lower chain-2O of the front of the machine from the direct drive of thechain. at the.

back. To convey a similar movement to the upper chains 20, a sprocketwheel 48 is secured on the shaft 37 around which sprocket a chain 49passes and around a sprocket wheel 50 secured on a shaft 51 extendingacross the width of the machine at the top. On the front end of theshaft 50 is secured a sprocket wheel 52 which drives by means of a chain53 the sprocket wheel 42 secured to rotate with the sprocket 24, whichdrives the chain 20 of the front of'the machine, and at the other end ofthe shaft 51 the direction of rotation is reversed by gears 54'55secured on shafts 51 and 56 on the latter one of which is secured asprocket wheel 57 driving by a chain 58 the sprocket wheel 42 'at theback of the machine. With this arrangement the adjacent or operativesides of the upper and lower chains 20 move in one direction at thefront of the machine and in the opposite direction at the back of themachine. By different location of the driving projections 22 of theupper and lower chains 20 at the back, from those atthe front, the chainprojections 22 of one set of chains will be in moving engagement with acard frame while those of the other will not. By the intermittentmovement imparted to the shaft 30 each card frame movement willalternate with a period of rest, that is the chains 20 will all movetogether for a distance represented by a revolution of the sprocketwheel of the shaft 30. During one movement, the card moving projections22 of the chains 20 in the front of the machine will engage and move acard holding frame from group 4 to group 3,

I during which movement the projections 22 of the chains 20 at the backof the machine are moving over their driving sprockets 24 and are not inengagement with a card holding frame. After a period of rest, theprojections 22 of the front chains 20 will be traveling over theirsprockets 24, and therefore out of engagement with a card frame, whilethe projections of the chains 20 at the back of the machine are inengagement with and are moving a frame from group 3 to group 4. Acontinual change of display from both faces of each card is thuseffected, and the position of each display is changed from the face ofone group to the face of the other, which change is advantageous from anadvertising point of view.

The frame includes upper and lower partition bars 11 which carry rollers13.
